Probabilistic Logic under Coherence, Model-Theoretic Probabilistic Logic, and Default Reasoning
2001
We study probabilistic logic under the viewpoint of the coherence principle of de Finetti. In detail, we explore the relationship between coherence-based and model-theoretic probabilistic logic. Interestingly, we show that the notions of g-coherence and of g-coherent entailment can be expressed by combining notions in model-theoretic probabilistic logic with concepts from default reasoning. Crucially, we even show that probabilistic reasoning under coherence is a probabilistic generalization of default reasoning in system P. That is, we provide a new probabilistic semantics for system P, which is neither based on infinitesimal probabilities nor on atomic-bound (or also big-stepped) probabil…
Imaging techniques for the vulnerable coronary plaque
2007
The goal of this article is to illustrate the main invasive and noninvasive diagnostic modalities to image the vulnerable coronary plaque, which is responsible for acute coronary syndrome. The main epidemiologic and histological issues are briefly discussed in order to provide an adequate background. Comprehensive coronary atherosclerosis imaging should involve visualization of the entire coronary artery tree and plaque characterization, including three-dimensional morphology, relationship with the lumen, composition, vascular remodelling and presence of inflammation. No single technique provides such a comprehensive description, and no available modality extensively identifies the vulnerab…
Forme del testo digitale
2017
L'articolo costituisce una riflessione sulla modellizzazione dei testi appartenenti alla nostra tradizione culturale in questa fase aurorale della Filologia Digitale e parte dalla domanda: che "forma" stiamo dando ai nostri testi? Vengono asplorati tre aspetti per cui i nostri modelli testuali riflettono i nostri presupposti culturali e tecnologici: in primo luogo, il modello gerarchico OHCO che sta alla base di TEI XML; in secondo luogo, il modello sequenziale alfabetico basato sulla stampa delle lingue occidentali, che sta alla base di Unicode. Un terzo aspetto, poi, è il meno esplorato nella ricerca: protocolli per la citazione testuale come CITE/CTS sono basati su corpora specifici. Per…

MOLECULAR CHARACTERIZATION OF MULTIDRUG-RESISTANT E. COLI ISOLATED FROM BACTEREMIA PATIENTS
2014
Background: Extraintestinal pathogenic Escherichia coli (ExPEC) bacteria have the ability to cause diverse and serious diseases, such as urinary tract infections (UTIs) and bacteremia; incidence of bacteremia is increasing globally. The emergence of multidrug resistance in E. coli is also becoming a global concern, with particular emphasis on E. coli sequence type (ST) 131, which is being increasingly reported in UTIs. Drug resistance is mediated by extended- spectrum β-lactamases (ESBLs), mainly of the CTX-M family, particularly CTX-M-15, and less frequently of the SHV and OXA families. Few studies are available regarding the characterization of E. coli strains causing bacteremia. Methods:…
Characterization of the first extended-spectrum b-lactamase–producing nontyphoidal Salmonella strains Isolated in Tehran, Iran
2010
The infections caused by Salmonella remain a significant public health problem throughout the world. b-Lactams and fluoroquinolones are generally used to treat invasive Salmonella infections, but emergence and spread of antibiotic-resistant strains are being increasingly notified in many countries. In particular, detection of extended spectrum b-lactamases (ESBLs) in Salmonella spp. is a newly emerging threat worldwide. This study was carried out to characterize b-lactamase–producing Salmonella strains identified in Tehran, Iran. Over the 2-year period from 2007 to 2008, 6 of 136 Salmonella isolates recovered from pediatrics patients, including three Salmonella enterica serotypes Enteritidi…
Los documentales científicos como instrumentos de educación para la sostenibilidad
2010
El objeto de este trabajo se centra en analizar el papel que están jugando y pueden llegar a jugar los documentales científicos que se difunden ampliamente a través de la TV, venta en quioscos, etc., en la formación de una ciudadanía consciente de los problemas a los que se enfrenta hoy la humanidad y preparada para participar en la adopción de las medidas necesarias
The use of spiral CT in the detection and management of a permanent maxillary first molar with single root and single canal : a rare occurrence
2017
A sound knowledge of the normal tooth morphology and its numerous variations is essential to the success of endodontic therapy. While extra canals and lateral canals are routinely encountered and documented, there also exists the rare possibility of a fewer number of canals than normal. Early detection of such an occurrence is critical to the prevention of iatrogenic errors during endodontic treatment. The advent of spiral CT as a diagnostic tool serves as a much needed confirmation to understand the complex three dimensional anatomy of teeth. The aim of this case report is to highlight one such case reporting unusual morphology of the permanent maxillary first molar displaying single canal…
Postmortem Imaging in Mass Disasters
2019
The term “mass casualty” in the forensic field refers to a sudden tragic event involving a large number of people; such an event determines the need to perform a large number of autopsy exams, possibly in a short time. Mass casualties tend to involve emergencies that are unexpected and result in stressful situation when even those with no or scarce interest or experience could be called to play a role. Radiology could be helpful in the task of identifying victims, in cooperation with a multidisciplinary team, usually headed by a forensic specialist.
